I've just uploaded a patched 1.61 release: 1.61.3. This should fix all the small regressions observed (so far) between 1.60 and 1.61. Please let me know if you find anything else that used to work in 1.60 and that does not work anymore in 1.61. Thanks. As usual, you can download the new version from http://geuz.org/gmsh/.
